This paper investigates the emission characteristics of hydrogen-enriched gasoline (95G5H2) under dynamic driving situations in order to fulfill growing need for cleaner and more efficient automobile fuels. study aimed investigate impact hydrogen addition on pollutant-specific emissions, including CO, CO2, HC, NOx, using a Nissan Qashqai that ran both pure (100G) 95G5H2. Emission statistics were obtained by computer simulations Worldwide Harmonized Light Vehicles Test Cycle (WLTC) applied AVL CRUISE software. The presents method comparing pollutants emitted combustion engine when powered regular fuel with hydrogen. tests performed real conditions, presented shows amount vehicle is directly motion, which allows effective comparison different 95G5H2 sharply reduces CO-, CO2-, HC-specific emissions 22.19%, 14.55%, 35.46%, respectively, compared 100G. However, NOx-specific increased 20.17%, suggesting compromise between higher efficiency burning temperatures. performs better urban cycles, plenty acceleration deceleration, usually results incomplete combustion. Although additional refinement needed cut demonstrate fuels have considerable potential lower vehicle-specific emissions. significant conclusions advantages fuels, practically environmentally, will help future development environmentally friendly transportation solutions.
